those in the upper jaw longer for the most part than those 



of the lower ; on each side beneath the mandibles a row of about 



eight minute pointed fleshy appendages, skin without scales, but 



closely covered with minute papillae. The general colour is of a 



pale lead hue, with minute and very distant spots of brown on 



the side of the head, pectoral fins, upper part of the side and 



back, and on the soft dorsal. There are also 3 or 4 narrow, 



short, transverse blue or black bands on each side. The first 



dorsal has the third spine elongate, and all extremely weak ; 



its colour is darkish, the other fins are yellowish ; the soft dorsal 



and anal very low, and the caudal long, pointed, and with 



about three narrow bars of brown. 



The average length of this curious looking fish is about 3 



inches.
